No communication between the two nodes in weblogic cluster

Question

Hi All,
We have installed weblogic cluster in our environment(LINUX 64-Redhat.5).On one node admin server ,managed server1,on second node we have managed server2.When we try to deploy application on one node it is not getting reflected in othe node.We have ran datagram test to check communication between 2 node.
Here we observed that listener and pulisher are picking wrong IPs not the server Ips.
can any one explain why and what is the problem.
thanks,
sudheer.

Hi Sudheer,
While performing the datagram test you mention the ports and ip so I am not sure how they are picking wrong ip and port. Follow the instructions to perform the test http://coherence.oracle.com/display/COH35UG/Performing+a+Datagram+Test+for+Network+Performance
Re the deployments, you need to ensure that multicast is enabled in your environment and both your managed server are in the same subnet otherwise you need to specify WKA for unicast communication. I am assuming that you are building SOA infrastructure as it internally uses Coherence for deploying applications and you can follow the instructions http://download.oracle.com/docs/cd/E15523_01/core.1111/e12036/extend_soa.htm#CHDEAFJH else use the intructions as mentioned here http://download.oracle.com/docs/cd/E17904_01/web.1111/e13709/features.htm
Hope this helps!
